Detect and report VM environment in crossystem

Add "inside_vm" command to crossystem.
x86: If there is no HWID and mainfw_type is "nonchrome", report that the
host is a VM. If HWID is present, it's not a VM.
ARM: Detection not implemented and so far no ARM VMs exist, always
report that the system is not a VM

crossystem: refactor VM detection to share across architectures

If there is no HWID and mainfw_type is "nonchrome", report that the
host is a VM. If HWID is present, it's not a VM. Make the detection
architecture-independent.

Gracefully handle cases where Chrome OS is running in a VM

Read from crossystem whether Chrome OS is running inside a VM or not. Do
not report an error if Chrome OS is in a VM, even if the HWID is
invalid, it is expected.
Add IsRunningOnVm() method similar to IsRunningOnChromeOS().
Cleanup:
	- more consistent naming
	- add unit tests to hwid_checker
